DROK LM2596HV Voltage Regulator DC Buck Converter 4.5-55V to 1.25-30V Adjustable Step Down Variable Volt Power Supply Stabilizers Universal Charger

hi everyone and welcome to this video so here i've got a random module that i picked out from the posters here supply box if you like and now let's take a look at it and and see what it is how it works etc so to start with why we got here we've got well I suppose the most important thing to look at is the chip so here the chip is LM to 596 s and I know I think I know what that is straight away it's a switching step-down converter that's just a gas though I'll have a look at the documentation in a minute so I believe that's one of theirs so therefore this whole module will be a step-down thing by the looks of it so the idea is you get a voltage and step it down to something more stable and it regulates as well so what have we got here so obviously you want to connect the voltage to that we've got a diode which I don't know the purpose of the diode capacitor which shall be a I think it'll
